IDENTIFICATION METHOD OF THE FOREST WITH SUPERIOR FUNCTION FOR THE WATER RECHARGE AND ITS SYSTEM

摘要

The present invention comprises the steps of: (a) measuring a volumetric moisture content according to at least two or more metric moisture tensions for a soil sample collected from a specific grid; (b) Parameters for applying the random forest model by driving the simulator program using the measured metric moisture tension and volumetric moisture content obtaining estimates of , a, n, m; (c) said parameters , estimating optimal hyperparameters of the random forest model using the estimated values of a, n, and m and input variables, and performing model learning; (d) the parameters of the following equation (1) through the trained random forest model , deriving predicted values of a, n, m; (e) said parameters , a, n, producing a forest water map by calculating a predicted value of the volumetric moisture content for each metric moisture tension using Equation 1 determined by the predicted values; (f) calculating the difference in the volumetric moisture content for each moisture tension of the metric, evaluating it as a water source nourishing function, and determining that the water source nourishing function is excellent if it falls within a certain range; and (g) displaying the forest determined to have excellent water source cultivation function as a map as a result of the determination of step (f). provides
